BOOT OR SHOE HEEL NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 313,345, dated March 3, 1885.

Application filed November 15, 1884. (No model.)

T 0 all whom it may concern.-

Be it known that I, EDWARD J. LE GAY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Boot and Shoe Heel N ailing Machines, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

This invention has for its object certain improvements in machines adapted to sustain in position the soles and heels of boots and shoes, and to secure the same together when so held by inserting suitable metallic fastenin gs therein, all as will, in connection with the accompanying drawings, be hereinafter more particularly described and claimed.

In said drawings, Figure 1 is a side eleva tion of a machine embodying my invention, the legs being in part broken away. Fig. 2 is a vertical section, taken as on line Z Z, Fig. 1, and as viewed from the left in that figure. Fig. 3 is an inverted or under side plan view of Fig. 1. Fig. 4 is a detached sectional elevation showing the clutch locking and liberating devices. Fig. 5 isan under side plan view of the heel carrying and adjusting mold and Fig.- 6 is a vertical section of the parts shown in Fig. 5, taken on line X in that figure. Fig. 7 is an enlarged vertical section taken as on line W, Fig. 2, through the shoe-supporting post and the nail holding and driving devices. Fig. 8 is a detached side elevation of the lower part of Fig. 7. Fig. 9 is a horizontal or transverse section taken on line V V, Fig. 7, and showing in elevation the interior parts below said line. Fig. 10 is a detached plan view of the interior plate shown in Figs. 7, 8, and 9. Fig. 11 is a detached edge elevation of one of the nail-drivers.

In said drawings, A represents the bed of the machine,which is mounted upon and supported by legs B, thereto secured at the respective ends.

0 represents a driving-pulley mounted to revolve loosely on shaft to. A series of clutch or ratchet teeth, I), are arranged around the axis of said pulley, to be engaged by the coincident teeth on the end of sliding clutch a, mounted on and interlocked with shaft a in the well-known manner of such clutches. Said clutch-collar c is moved into and out of contact with the teeth I) of pulley O by the arm (Z engaging in the concentric groove in c, said arm being rigidly mounted on the sliding rod 6, supported in bracket m, and which is forced toward said pulley by the action of a suitable treadle connected with rod j, which, at i, is connected with the horizontal arm of anglelever f, pivoted and supported at g, and whose vertical arm is pivoted at h to said rod e, as shown in Fig. 1. Said rod is returned by the expanding action of helical spring 70, axially mounted on the rod between the hanger or bracket m and setcollar Z, secured on the rod.

For the purpose of locking said clutch and pulley together and releasing them at the conclusion of each revolution of the pulley and its shaft a, an arm, n, is pivoted in hanger p and extends across rod 6, it being held upward in contact therewith by the contractile force of spring q, said arm being in contact with the rod proper when the clutch is in con- 7 5 tact with the pulley; but when they are disconnected the arm bears against collar 8 of the rod, as shown in Fig. 3. A cam, t, secured on shaft a, is so positioned that it will engage arm n and force it below or out of contact with said collar 8. Therefore, when the operator, through the action of the treadle acting on rod j and the angle-lever f, shall force rod 6 toward pulley O, and by the action of its arm d forces the clutch 0 into contact with the pulley, the collar 8 will be withdrawn from contact with the arm a, which will, by its spring g, be raised against rod 6, thereby locking clutch c with the pulley and allowing the operator to release the treadle, in order that when cam t on shaft or depresses arm it below collar 8, the spring k, acting on collar Z, will disengage the clutch, and so arrest the movement at the completion of the revolution.

For the purpose of converting the rotary motion of shaft a into reciprocatory action of the nail-driving devices, a vertical rod, to, is arranged to slide in bearings and to extend above bed A, as shown in Figs. 1, 2. In an enlargement, 'v, of this rod is formed an open :00 slot, w, in which is arranged the sliding block :v, in which is arranged the crank-pin y of shaft a, the same being so arranged that the rotation of said shaft will, through said wristpin and block, impart to rod u a vertical reciprocation in the well-known manner.

' The shoe and heel supporting and nail carrying and driving devices are described as follows:

Upon bed A is secured the standard 2, in the head of which is fitted the plunger 5, in which is threaded the screw 4, provided with and actuated by a hand-wheel, as shown, said screw being held from lineal movement by its collar 7, which is seated in the cap secured upon the standard 2, as shown in Fig. 2.

In the lower end of plunger 5 is secured the stem or shank of slotted plate 8 by the setscrew 9, and to this plate is bolted the heelsupporter 10, as shown in Figs. 1, 5, 6, said supporter being formed to receive and sustain the heel in its cavity 6, as shown in Figs. 2, 5, 6, and by means of the width and length of the slot in plate 8 the supporter may be adjusted and confined by the bolt 11 in the position desired.

Upon the base 3 of the standard2 is secured a plate, 12, integral with which is formed the standard-like shell 13, in which is fitted to slide freely the plunger 14, the same being held from rotary displacement by plug-screw 15 threaded therein, and projecting through a slot, 16, in the shell.

For the purpose of graduating the height to which the plunger 14 and the drivers thereby carried shall rise, a screw, 17, is threadedin the lowerpart of the plunger, and so arranged that reciprocating rod a, driven by crankshaft a, as already stated, will engagethe head thereof, and thereby raise the plunger. In the top of shell 13 is seated and secured by screws, as shown, the head 18, in which and in plunger 14 is centrally seated the coiled spring 19, which depresses the plunger when rod u descends. Through head 18 a series of longitudinal passages, 20, are formed, to receive the drivers 21, which are reduced or necked at 22, to be seated in the upper and undercut slots 24, arranged around cap 23 in the same order as are passages 20 in head 18. Said drivers being thus interlocked in cap 23, which is secured to plunger 14 by screws, as shown, will rise and descend therewith, and by thus interlocking said devices in cap 23 they can be readily removed and replaced, and need not be closely fitted therein, as a limited freedom is beneficial.

Although drivers 21 may be formed with any desired configuration of cross-section, yet for the purpose of driving staple-like nails like or similar to that shown at 25, Fig. 7, they are formed with an elliptic cross-section, and their upper end is oblique to their axis to conform to the curvature of the insole, where the nails are driven; and I arrange said openings 20 for the drivers in the manner shown, so that lines passing through the two arms of each nail will be nearly at a right angle to a line tangential to the heel at that point, or nearly radialfrom the center of the heel.

In practice the inverted boot or shoe is placed upon the supporting-standard with the heel portion of the insole resting upon head 18 and with the toe pointing directly from standard 2. The heel is seated in holder 10, and screw 4 is actuated to press the heel firmly upon its seat on the shoe. Then by actuating the treadle, clutch c is interlocked with the driving-pulley and the crank forces up rod u, and thereby plunger 14 and the drivers 21, which, acting on the nails, (which are placed in passages 20 before arranging the shoe in place,) they are forced through the soles into the heel confining the two firmly together, and by the adj ustment of screw 17 in plunger 14 the exact degree of force required to be applied to the nails is secured.

The cam t on the driving-shaft a is so positioned that the locking-arm n will be thereby depressed and rod e released at such point of the revolution of the crank as will leave rod to at its lowest point, the spring 19 tending by its action on plunger 14 to check rod 10 at such lowest point.

If preferred, screw 4 may be threaded in a bracket hinged to standard 2, whereby. instead of raising the heel-supporter to allow the removal and replacement of the boot or shoe on the cap 18, the screw may be but slightly raised and then swung out of the line of the shoe. I

I claim as my invention- 1.
